BMW Ghost Driver Warning

GDW uses the map to recognize a situation when the vehicle is
moving in the wrong direction on one-way roads (e.g. highways). The
driver is warned acoustically, as well as visually on the Head-up
Display and the Central Information display. In addition, the
position of the ego-vehicle is sent via a Vehicle-to-Vehicle
communication channel to other cars in the vicinity, informing other
drivers about the presence and exact location of this danger. Using
Vehicle-to-Infrastructure communication the location of the Ghost
Driver is sent to a Service Centre, which in turn can alert the
authorities, as well as other entities who are able to distribute
warnings in the wider area.
